CCNA Practice Question: At a large enterprise observes repeated spikes in…
This 200-301 practice question tests your understanding of 200-301 exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer at a large enterprise observes repeated spikes in latency on the core network every weekday at 10:00 AM, but no corresponding increase in overall bandwidth utilization. The engineer wants to use AI/ML to automatically identify the root cause and take corrective action without manual intervention. Which AI/ML concept best describes this approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Intent-based networking
The scenario describes using AI/ML to detect a recurring anomaly (latency spikes) and automatically respond. This is a combination of anomaly detection (identifying the unusual pattern) and intent-based networking (where the network continuously validates and adjusts to meet operational intent). Predictive analytics would forecast future spikes but does not automatically correct them. Intent-based networking is the broader framework that includes closed-loop automation, but the specific detection of the spike is anomaly detection; however, the question asks for the concept that 'best describes this approach' of automatic identification and correction, which is the essence of intent-based networking's closed-loop assurance.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Anomaly detection
Why it's wrong here
Anomaly detection identifies unusual patterns (like latency spikes), but it does not include automatic corrective action. The scenario requires both detection and automated response.
- ✓
Intent-based networking
Why this is correct
Intent-based networking (IBN) uses closed-loop automation to continuously monitor the network, detect when the actual state deviates from the intended state (e.g., latency spikes), and automatically reconfigure the network to restore the intent. This matches the scenario of automatic identification and correction.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
Predictive analytics
Why it's wrong here
Predictive analytics forecasts future events (e.g., predicting when a link will fail), but it does not automatically take corrective action. The scenario involves detecting and correcting an existing anomaly, not predicting a future one.
- ✗
Machine learning classification
Why it's wrong here
Machine learning classification categorizes data (e.g., classifying traffic as normal or anomalous), but it does not inherently include automated corrective actions. The scenario requires a system that both detects and corrects.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

✗Anomaly detectionWrong answer — click to see why▾
Why this is wrong here
Anomaly detection only identifies the problem; it does not automatically take corrective action.
✗Predictive analyticsWrong answer — click to see why▾
Why this is wrong here
Predictive analytics focuses on forecasting, not on real-time detection and automatic remediation.
✗Machine learning classificationWrong answer — click to see why▾
Why this is wrong here
Classification is a component of anomaly detection but does not provide the closed-loop automation needed for automatic correction.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Scenario analysis trap
Anomaly detection identifies unusual patterns (like latency spikes), but it does not include automatic corrective action. The scenario requires both detection and automated response.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 200-301 NAT questions on configuration and troubleshooting.
